I bought a used 2000 F4 and I cannot find a fuel cutoff switch. Is it fuel injected? I thought it was just the F4i's that were injected? It has a full Jardine exhaust on it and the guy I bought it from was the second owner and he said he didn't think the carb was rejetted. That's my only reason for concern. Any help is appreciated in locating the fuel cut off (if there is one).
